Latest Patents

Watanabe's latest patents include a method of manufacturing glass articles, a method of manufacturing glass gobs, and a method of manufacturing optical elements. His innovative approach involves creating high-quality preforms from glass melt, which are then used to manufacture glass elements such as lenses through press molding. The process includes continuously separating glass gobs from a glass melt flow that flows out of a nozzle. The separated glass gobs are formed using glass forming members that can move either intermittently or continuously. A support member is designed to approach the front end of the nozzle, receiving the glass melt flow and dropping it more rapidly than the flow rate to separate a glass gob. This gob is then transferred to a glass forming member to mold a glass article. Additionally, he has developed a method of producing a glass gob by continuously dropping molten glass from a nozzle while applying a gas flow to create wind pressure, aiding in the production process.
